Reviews for Cefdinir to treat Sinusitis

Sort by:

"I suffer from multiple sinus infections every year. Three days ago I was prescribed cefdinir for the first time. It has caused unbearable nausea and diarrhea. After hearing that it has done the same for so many others, it angers me that a doctor would even consider prescribing this drug when there are other options that work better and do not have unacceptable side effects. Cefdinir is a failure in the field of medicine."

"Started this to fight a sinus infection. 4 days in seemed to improve. Only negative was a bad headache. Night 4 horrible night sweats and chills to the bone. I couldn't function at work and was still getting chills and stomach cramps. Then the constant diahrrea started. Day 5 I had a fever of 102 to go along with body shakes, headache and still diahrrea. I thought it was the flu so continued medication but by day 7 have had no relief from it, called my Dr and she told me to stop meds immediately. I just stopped and hoping for some relief. I am dehydrated and weak and still can't leave the bathroom for more than 20 minutes! Bad reaction and hoping for some relief!"

"I saw my Dr for bad sinus infection. He prescribed cefdinir. I took the first one and within a short while was violently vomiting, sweating profusely, very weak. Called 911 to help get me off the floor into a chair to be wheeled to the car. Went to the emergency room. ER doc said nausea & vomiting due to the serious upper respiratory infection, but I see here it may have been the cefdinir. If any of the future doses make me sick, I'm going to ask for different antibiotic."

"This is day 3 of taking the medication, and although my sinusitis symptoms have majorly improved, I now have severe diarrhea and a pounding headache every day. Between the two I can barely function. If it doesn't improve by tomorrow I'm going to call the Dr's and hopefully switch to something else."

"Terrible, terrible antibiotic. I took Z pack for my sinus infection, which usually helps but didn't this time so my doc put me on cefdinir. No problems until the 3rd day I woke up with the most terrible diarrhea I've ever had. Same the following day. It's almost 3 weeks later and I still have the diarrhea and have gone to the ER once for iv fluids to help with my dehydration. I would NOT recommend."

"I am on my 4th day of the pill and although my sinusitis is almost 100% gone, I have the worst diarrhea I've ever experienced in my life. I cannot be away from the bathroom for more than 30min-an hour. I feel better physically, but this side effect is one to look out for."

"I had taken this drug in the past, it made me vomit violently and diahreah. When it was prescribed for me recently I had forgotten that this was the drug that made me so sick. I took one capsule and within 3 hours was violently ill, massive diareah and vomiting...I was alone and could not even get to my phone for help, I layed on the floor of my shower for hours having episode after episode. It is nearlly 24 hours after taking it and I am in such a weakened state I will not be getting out of bed. I feel I probably should have called 911 and gone to the hospital, I still am so dehidrated. This is an evil drug!"

"Day 8. I have had the most severe sinus/double infection of my life and this medication has helped tremendously! I was worried it wasn't working at first but by day 5, I felt so much better!! On the down side, I have terrible headaches almost all day. I'll skip a day then the headache is back. Ibuprofen helps a little bit not much. Dizziness is terrible also. I have a little confusion and frustration at times. Its not too bad. Just the AWFUL headaches but I remember how bad my infections were before this medicine and it's worth it. Slight diarrhea but no big deal."

"I noticed after the second day of taking Cefdinir 300 mg, I started to experience bad headaches. My sore throat feels better, but my head aches everyday. So, now that I know what is making my head hurt so bad I am discontinuing the use of this medication. I had no issues with Amoxicillin, I will ask if he can change my meds over."

"When taking this medication, I experienced night terrors. I don't see it anywhere listed as a side effect, so that's my experience."

"Within 4 hours of taking the first dose of this medication my coxcyx began to itch, which was odd. About six hours after taking the first dose I had terrible, intense, painful itching that was uncontrollable throughout my groin area including vaginal and anal itching. The more I scratched the more I itched. I tried Ice, and benedryl which helped a bit so I didn't go to the hospital. In the morning the doctor changed the antibiotic and I was also given something to successfully treat for the worst yeast infection I have ever had. Several years later I had the same experience (I forgot ) and now list cefdinir as a drug allergy. I am not allergic to any of Cefdinir's relatives, or penicillin."

"Worked great for me, knocked out my sinus infection and bronchial infection. I read the negative reviews and ate lots of yoghurt to keep my stomach from hurting."

"Been taking this for five days. The pressure in my sinus is lessening, and my fever is gone, but mucus production has increased, and so now my cough is worse. Does this mean it's not working? The best way I've found to avoid the adverse digestive effects (vomiting, etc) is to take a strong probiotic to replenish what the antibiotic kills. You can ask your doctor for a prescription strength probiotic (they prescribe them for patients with ulcerative colitis) or find them in pill or drink form at a health food store. "

"I am on Day 6 of this antibiotic. I am not a huge fan of antibiotics but my vertigo and head pressure from the sinus infection was enough to get me on them. For the first 2 days I had no vertigo and head pressure, but now I experience some of it on and off the day. So I use a Neti Pot to clear out sinuses. Two days ago I had Post Nasal Drip where I ended up throwing up mucus in the middle of the night. With my experience, I have noticed a loss of appetite and have lost about 5-6 pounds. If I do not take the capsule with food I will end up with heartburn. I am looking forward to being over with this (4 more days to go) I take a probiotic in between the doses for my digestion."

"I was prescribed this medication for sinus infection and fluid in ear. I have on my charts that I am allergic to penicillin but not sure of reaction. So doctor said this has 1% of penicillin derivative. So I tried it! First 2 days sinus seemed to get better. Then 6, and 7th day I had horrible a headache, ear aches, facial skin burning, chills and sweats. I couldn't lift my head off pillow. Took myself off the medicine and next day I was feeling better. Still have a lot of congestion but the pain in my head is gone. I feel like my head was deflated. This has to be an allergy! I learned my lesson."

"My doctor prescribed for sinusitis. After finishing the first round I was still having problems and called the doctor. He called in another round of the same prescription which I finished a week ago. Still having the same problem and called today. He called in Omnicef again and I am not sure if I will even pick it up. I take the full prescription as prescribed."

Omnicef (cefdinir): "Fantastic at clearing the sinus infection. I'm on day 4 and it's almost completely gone. The first two days were miraculous. But then. Starting day 3 ... My stomach and intestines are rumbling almost constantly and I'm "pooping" brown water 5+ times a day. I'm also utterly exhausted and weak, making it virtually impossible to actually do anything. If this gets much worse, I'm going to have to stop using this before the 10-day course runs out."

"I have been taking Cefdinir for three days now. The second day taking it I felt like I was getting better but the third I felt sick again. I was diagnosed with sinusitis and an ear infection. I did not have drainage in the back of my throat until I started taking this antibiotic. I'm hoping to feel better soon and hopefully Cefdinir works."
